Start with a nickel then after shooting for a  while try the dime shape.

Or do the quarter, nickel, then the dime.

If you start with the dime, you'll notice a big difference in how easy you
can spin the cue ball, but you may also experience that your shooting
accuracy was degraded.

Cheers,
Jim

Nickel on a14 mm tip.....Dime on 12. Personal preference on 13

::nickel or dime?
::whatcha all think?

Predator claimed when they first launched their product that
Iron Willie had been used to determine that DIME was better.
I don't know what "better" means. I've been using dime for 5
or 6 years. It's much harder to maintain, so I'm probably at
nickel pretty often.

One real difference is that, with a smaller radius, e.g.,
dime, your contact point on the cueball is further out from
center for a given amount of tip offset. I suspect this is
what led Predator to say dime was better. Iron Willie would
get more spin with the same offset with a dime than with a
nickel radius.

I agree.  I think this is a small effect, but one that a player would notice.  

If you look at the Predator web site you will see one of their contact strips
that supposedly shows a difference in squirt for tips with different curvature.
 They are a little unclear about what exactly was done to generate that data,
or about how consistent are the results, but at least they do show something to
support their claim that a dime radius is better than a nickel radius.  Tip
radius does not appear in the squirt equations that have been posted here in
RSB, and I don't understand the mechanism by which tip radius might affect
squirt.

Well, I am way out of my league here, but could it be something as
simple as what both you and Tom agree on:  that your contact point on
the cueball is further out from center for a given amount of tip
offset?  Thus, contact point further out, therefore more english and
more squirt.  I would think this would be so, since Iron Willie might
be set for the *same* amount of tip offset with both dime and nickle.

What you've said makes sense, but I don't think that's what the
Predator folks are saying.  I think they're saying that a dime radius
tip is "better" because it produces less squirt, not more spin.
(Although they also claim more spin with their shafts, which I don't
believe.)

I have not been to the Predator site to see what they are
saying lately, but think about it. A dime radius lets you
get the same amount of spin with less APPARENT offset. How
much spin you get is determined by how far out from center
the TIP/BALL CONTACT POINT is. Since the dime radius curves
more sharply, for a given amount of STICK OFFSET, your ball
contact point is further out from center. In other words,
your stick doesn't have to be offset as far to get the same
spin with a dime as with a nickel.

Now, the other thing that's happening is that with less
stick offset, your contact point on the TIP is closer to the
center of the shaft. Someone else can confirm or refute the
physics, but it certainly seems true to me that you will get
less squirt as your tip contact point approaches the center
of the tip.

Summary:

1. Upside: Dime radius gives you more spin for a given
amount of stick offset. Downside: More spin with less offset
means you have to be more accurate with your tip placement.
2. Upside: Dime radius gives you less squirt for that same
amount of spin because the tip contact is closer to the
center of the shaft. Downside: Because you get offset
effects with less offset with a dime, you have to be more
accurate with your tip placement. In other words, you might
think you are hitting a hair to the right of center and
don't have to adjust for squirt, but you're really hitting a
little more to the right of center, so maybe you do need to
adjust.

I don't think these are large effects, but they are
nonetheless, real.

I think everything you've said is true, Tom.  That's why I said it made
sense when Gideon said it.  I was just commenting on whether that's what
Predator is saying or not.
